Description

Technical Field

[0001] This invention belongs to the technical field of LED vehicle lights, and specifically relates to an LED interactive vehicle light. Background Technology

[0002] Vehicle lights serve the dual purpose of illumination and signal transmission. With the development of the automotive industry, vehicle lights have evolved from halogen lamps to LED lamps, and from direct beams to dynamically changing lights that can indicate the vehicle's driving status.

[0003] Existing automotive LED lights use a single, integrated LED panel as their light-emitting element, controlled by a single driver. If either the LED panel or the driver malfunctions, the entire automotive LED light assembly will fail to display properly, thus hindering normal information interaction. Furthermore, the varying installation areas, positions, and available space on interior panels and exterior lighting strips across different vehicle models make it difficult for existing integrated LED panels to meet the unified assembly requirements of different vehicle interiors and exteriors. Moreover, beyond simple traffic signal transmission, people demand personalized expression from vehicle lights, a need that current automotive LED lights cannot satisfy.

[0004] Therefore, in view of the above-mentioned problems of existing vehicle LED light groups, the present invention discloses an LED interactive vehicle light. Summary of the Invention

[0005] This invention discloses an LED interactive vehicle light that can be flexibly assembled to meet the interior and exterior styling requirements of different vehicle models. At the same time, each LED light-emitting unit is individually controlled by an independent driver, avoiding the complete loss of function of the entire vehicle LED light group. Furthermore, this invention can be installed at the front and rear of the car without affecting the transmission of conventional traffic signals, realizing personalized expression of vehicle lighting.

[0006] This invention is achieved through the following technical solution: An LED interactive vehicle light includes a rear housing. A lamp cover assembly is fitted onto the front side of the rear housing. The lamp cover assembly includes an opaque area at the edge and a completely black, light-transmitting area inside the opaque area. An LED light panel assembly and a driver board are arranged sequentially from front to back between the lamp cover area and the rear housing. The LED light panel assembly includes a plurality of sequentially connected LED light panel units. The driver board is inserted into the rear side of each LED light panel unit. An LED controller is arranged on the rear side of the rear housing and is connected to the driver board.

[0007] To better realize the present invention, the LED light board unit further includes a PCBA circuit board, a splicing unit, and LED array beads. LED array beads are provided on the front side of the PCBA circuit board, and splicing units are provided at the edge of the PCBA circuit board. Adjacent PCBA circuit boards are spliced ​​together through splicing units.

[0008] To better realize the present invention, a connector assembly is further soldered on the rear side of the PCBA circuit board, and the PCBA circuit board is connected to the driver board through the connector assembly.

[0009] To better realize the present invention, the connector assembly further includes a connector port and connector terminals. The four rear corners of the PCBA circuit board are provided with connector ports, and the four front corners of the driver board are provided with connector terminals corresponding to the connector ports. The connector terminals are plugged into the connector ports.

[0010] To better realize the present invention, the front side of the PCBA circuit board is covered with a black transparent potting compound layer, and the height of the black transparent potting compound layer is higher than the height of the LED array beads.

[0011] To better realize the present invention, the gap between adjacent PCBA circuit boards is equal to the spacing between two adjacent columns of LED beads in the LED array.

[0012] To better realize the present invention, the lampshade assembly further includes a lampshade body and a lampshade bracket. A snap-fit ​​protrusion is provided at the rear edge of the lampshade bracket, and a snap-fit ​​groove is provided at the front edge of the rear shell. The snap-fit ​​protrusion and the snap-fit ​​groove are snapped together. A hollow light-transmitting area is provided inside the edge of the lampshade bracket. A lampshade body that integrally covers the area where the LED light panel assembly is located is fixedly installed on the front side of the lampshade bracket.

[0013] To better realize the present invention, a limiting flange is further provided on the rear side of the hollow light-transmitting area along the contour of the hollow light-transmitting area. The limiting flange abuts against the front edge of the LED light panel assembly, so that the internal installation structure cannot be seen.

[0014] To better realize the present invention, a mounting slot is further provided on the rear side of the rear shell, an LED controller is fixedly installed inside the mounting slot, a controller housing is provided on the rear side of the LED controller, and the controller housing is detachably installed on the rear side of the mounting slot.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention forms an LED light panel assembly by splicing together several LED light panel units of the same or different specifications and shapes. Each LED light panel unit is driven by a separate driver board. Unless all driver boards and LED light panel units are damaged, the vehicle-mounted LED light assembly can always maintain a certain level of display and interactive functionality, preventing complete loss of function. Simultaneously, this invention is compatible with different vehicle models and their varying installation areas, positions, and space requirements, flexibly allowing for the adaptive splicing of LED light panel units of the same or different sizes and shapes, thus improving the applicability of the vehicle-mounted LED light assembly. Although the LED light panel assembly uses a split-splicing structure, the lampshade assembly uses an integrated, through-type structure. The overall illumination component completely covers the luminous area of ​​all LED light panel units, resulting in a smoother transition between the vehicle-mounted LED light assembly and the vehicle's interior, enhancing the overall integrity and consistency of the interior and exterior.

[0018] Example 1: One embodiment of this example is an LED interactive vehicle light, such as... Figures 1-4 As shown, the device includes a rear shell 5, on the front side of which a lampshade assembly is fitted. The lampshade assembly includes an opaque area at the edge and a completely black, light-transmitting area inside the opaque area. An LED light panel assembly and a driver board 4 are arranged sequentially from front to back between the lampshade area and the rear shell 5. The LED light panel assembly includes several sequentially connected LED light panel units 3, and the driver board 4 is inserted into the rear side of each LED light panel unit 3. An LED controller 6 is arranged on the rear side of the rear shell 5, and the LED controller 6 is connected to the driver board 4.

[0019] The LED controller 6 inputs control signals to the driver board 4, which in turn drives the LED beads on the corresponding LED light panel unit 3 to light up or turn off according to the set patterns and shapes, thereby conveying different information. Depending on actual usage requirements, several LED light panel units 3 of the same or different specifications and shapes can be sequentially spliced ​​together to form an LED light panel assembly. The assembly is then fixed in place by the lampshade assembly and the rear shell 5. The lampshade assembly is a one-piece, continuous structure that covers all areas of the LED light panel assembly, forming a continuous overall structure that is consistent with the car's styling and ensures a uniform appearance. Each LED light panel unit 3 has a corresponding driver board 4 connected to its rear side, allowing the driver board 4 to independently drive each LED light panel unit 3 for display.

[0020] The lamp cover assembly is a black translucent plastic part, which is used to shield and protect the internal structure when the LED light panel unit 3 is not lit, so that the internal structure cannot be seen directly, thus creating a consistent look with the overall vehicle design.

[0021] Furthermore, a mounting slot is provided on the rear side of the rear shell 5. An LED controller 6 is fixedly mounted inside the mounting slot. A controller housing 7 is provided on the rear side of the LED controller 6, and the controller housing 7 is detachably mounted on the rear side of the mounting slot. The controller housing 7 is detachably engaged with the rear side of the mounting slot via a snap-fit ​​structure, thereby enabling convenient assembly and disassembly of the controller housing 7 and facilitating convenient maintenance and replacement of the LED controller 6. It should be noted that the driver board 4 and the LED controller 6 are existing commercially available products, and the structure of the driver board 4 and the LED controller 6 themselves is not a technical improvement of this invention. Therefore, the specific structure of the driver board 4 and the LED controller 6, as well as the control principle of the LED beads, will not be described in detail here.

[0022] Example 2: This embodiment discloses an LED interactive vehicle light, which is an improvement on embodiment 1, such as... Figure 2 and Figure 5 As shown, the LED light board unit 3 includes a PCBA circuit board 31, a splicing unit, and LED array beads 32. The front side of the PCBA circuit board 31 is provided with LED array beads 32, and the edge of the PCBA circuit board 31 is provided with splicing units. Adjacent PCBA circuit boards 31 are spliced ​​together through splicing units.

[0023] The PCBA circuit board 31 has lugs at its edge with connection holes. A positioning post is located on the front side of the rear housing 5, corresponding to the connection holes on the lugs. The positioning post has a coaxial threaded hole. By passing a connecting screw through the connection hole or threading it into the corresponding threaded hole, the PCBA circuit board 31 is fixedly mounted on the front side of the rear housing 5. Depending on the specific application requirements, several LED array beads 32 arranged at different spacings and shapes are printed and soldered onto the front side of the PCBA circuit board 31. A splicing unit is located at the rear edge of the PCBA circuit board 31, including splicing terminals that can interlock, enabling interconnection between adjacent PCBA circuit boards 31. Based on the final interactive display requirements, different numbers and shapes of PCBA circuit boards 31 can be spliced ​​together to form an integrated light assembly.

[0024] Furthermore, the front side of the PCBA circuit board 31 is covered with a black translucent potting compound layer. The height of this layer is higher than that of the LED array beads 32, ensuring that both the PCBA circuit board 31 and the LED array beads 32 are beneath it, thus maintaining a large black area for the LED light board unit 3. This prevents users from directly seeing the internal components through the lampshade assembly when the LED light board unit 3 is off. Simultaneously, the black translucent potting compound layer also protects the beads, effectively absorbing and buffering mechanical stress, preventing solder joints from breaking due to long-term vibration, and preventing components from loosening or being damaged by impact. This is crucial for vehicles traveling on bumpy roads. Moreover, the LED light board unit 3 experiences temperature changes during operation, leading to thermal expansion and contraction of the materials. The black translucent potting compound layer helps to withstand this deformation, releasing internal stress and preventing cracking at rigid connections. Meanwhile, the black transparent potting compound itself is insulating, which can prevent creepage and breakdown between high-voltage and low-voltage components inside the headlight, and can also prevent short circuits between component pins caused by dust and moisture, thus ensuring the stability and electrical safety of the drive circuit.

[0025] Furthermore, the gap between adjacent PCBA circuit boards 31 is equal to the spacing between two adjacent columns of LED array beads 32, ensuring the continuity and consistency of the display effect and avoiding display distortion and fragmentation problems.

[0026] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0027] Example 3: This embodiment discloses an LED interactive vehicle light, which is an optimization based on embodiment 1 or 2, such as... Figure 2As shown, a connector assembly 8 is soldered onto the rear side of the PCBA circuit board 31, and the PCBA circuit board 31 is connected to the driver board 4 via the connector assembly 8. The connector assembly 8 includes connector ports and connector terminals. Connector ports are provided at the four rear corners of the PCBA circuit board 31, and connector terminals are provided at the four front corners of the driver board 4 corresponding to the connector ports. The connector terminals are plugged into the connector ports.

[0028] The connector terminals are equipped with pins. The contact terminals are inserted into the connector ports to connect the pins to the contact points inside the connector ports, thereby establishing a connection between the driver board 4 and the PCBA circuit board 31. During installation, the smaller driver board 4 is first fixedly mounted on the front side of the rear housing 5. Then, the connector ports on the PCBA circuit board 31 are aligned with the connector terminals on the driver board 4 and inserted to establish electrical connection between the PCBA circuit board 31 and the driver board 4. Finally, the PCBA circuit board 31 is secured.

[0029] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.

[0030] Example 4: This embodiment discloses an LED interactive vehicle light, which is an optimization based on any one of embodiments 1-3, such as... Figure 4 As shown, the lampshade assembly includes a lampshade body 1 and a lampshade bracket 2. A snap-fit ​​protrusion 21 is provided on the rear edge of the lampshade bracket 2, and a snap-fit ​​groove is provided on the front edge of the rear shell 5. The snap-fit ​​protrusion 21 is snapped into the snap-fit ​​groove. A hollow light-transmitting area is provided inside the edge of the lampshade bracket 2. The lampshade body 1, which integrates the area where the LED light panel assembly is located, is fixedly installed on the front side of the lampshade bracket 21.

[0031] The lampshade bracket 2 is a pure black injection-molded part. The lampshade body 1 and the lampshade bracket 2 are integrally formed by secondary injection molding. The edge of the lampshade bracket 2 is an opaque area used to install the snap-fit ​​protrusion 21. The lampshade bracket 2 is installed on the front side of the back shell 5 by the corresponding snap-fit ​​of the snap-fit ​​protrusion 21 and the snap-fit ​​groove. The hollow light-transmitting area set inside the edge of the lampshade bracket 2 is used to cooperate with the lampshade body 1 to transmit light. The lampshade body 1 is a black light-transmitting plastic part. When the LED light panel assembly is turned off, the internal components can be hidden through the lampshade body 1, preventing the user from directly seeing the internal components of the lampshade body 1.

[0032] Furthermore, a limiting flange 22 is provided on the rear side of the hollowed-out light-transmitting area along the contour of the hollowed-out light-transmitting area, and the limiting flange 22 abuts against the front edge of the LED light panel assembly. By abutting against the side edge of the LED light panel assembly through the limiting flange 22, the position of the LED light panel assembly is restricted, ensuring the final display position of the LED light panel assembly, and also preventing the internal installation structure from being seen from the connection gap.

[0033] The rest of this embodiment is the same as any one of embodiments 1-3, so it will not be described again.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
